Homework #1

Questions:

  1. Find your way to one or more of the College of Engineering (COE) computer labs, maintained by Engineering Network Services (ENS). These are different from the labs maintained by the residence halls and the campus-wide computing network (ACNS). A list of the ENS computer labs can be found at the ENS lab facilities page. While you are in the lab, do the following:

    1. Login to RamWeb. Under the gray heading “Records”, click on the link for “Change My Email Address”. Make sure that the email address shown here is one that you check daily. Change it if necessary. Monitor this email for important announcements from classes, the CBE Department, and the COE.

    2. Login to Canvas and browse to the webpage for CBE 101. Carefully read the syllabus, course policies document, policies about electronic communications, and the guidelines for homework and lab report submissions .

  1. According to the syllabus, what are the conditions necessary to receive homework credit? How does the iClicker quiz fit into this?

  1. Is it permissible to use an online solution or solution manual to solve homework or extra credit assigments? What resources are permitted under CBE 101 instructor – and university – guidelines?

  1. According to the Academic Integrity section of the Course Policies document, what four measures will be taken if a student is caught cheating in CBE 101?

  1. Describe the acceptable use of cellphones and laptops in CBE 101.

  1. According to the course syllabus, which of the following are acceptable ways to submit homework? (Choose all that are correct.)

    1. Emailing a scanned copy of my homework to Claire Lavelle.

    2. Writing solutions on 8 1/2” by 11” paper.

    3. Fastening multiple pages torn from a spiral notebook, by folding the corner of the pages.

    4. Working with a group classmates to complete the assignment, submitting separate assignments for each student in the group, and indicating the names of the people who worked together on each student’s submission.

  1. A student in high school has asked you “What is a chemical and biological engineer?” Answer this question in a few sentences. Include each of the following in your answer

    • at least one example of technologies or industries to which that chemical and biological engineers have made or are making significant contributions,

    • at least one example of a future challenge facing our society that chemical engineers might address, and

    • a brief description of one course that chemical and biological engineering students like yourself will take in college. (Choose a course that is relatively specific to chemical and biological engineering - not something like “composition”.)

Questions 8 and 9 are based on textbook material.

  1. Complete Reading Questions 1 and 2 from Chapter 2 (top of page 25) of Introduction to Chemical Engineering: Tools for Today and Tomorrow (5th Edition).

  1. Consider the chemical process described in section 14.3 of Introduction to Chemical Engineering: Tools for Today and Tomorrow (5th Edition), beginning on page 221. Read the section titled “Process description” on page 221. Make a process flow diagram (PFD) and accompanying stream table. Your stream table will have some entries that are unknown (e.g., you are only given some of the stream temperatures and compositions). You should include all of the known, given quantities in the stream table (e.g. composition of the feed and three product streams), but it is acceptable to leave the unknown quantities blank.

    Model your PFD after the examples in Chapter 2 (e.g., Figures 2.6 and 2.8), using symbols from Figure 2.5. The “well-mixed, isothermal reactor” can be drawn as a “jacketed closed vessel with agitator”. The separation system can be drawn as a single “tray column” with only one inlet stream and three outlet streams. In Figure 2.5, the numbers shown on the tray column (1, 14, and 35) are examples to show you how the trays are numbered from top to bottom. Not all such columns have the same number of trays, so the numbers should be omitted in your PFD, since you do not know how many trays there will be.

Review your responses to all of the homework questions before class so that you are prepared for the quiz on Tuesday!
